This invention relates to 3 Claims.

improvements in shipping cases, and more particularly to containers or cases of the type designed especially for holding milk bottles.

In shipping cases for milk bottles and the like, it is customary to divide the interior of the case into individual compartm gitudinal and transverse ro tal planes. It has also be force the edge portions of channels and to reenforce with metallic angle members.

ents by means of londs in different horizonen customary to reenthe case with metallic the corners of the case Heretofore the angles have been secured tothe walls of the case by rivets, and in addition, to someextent,

rivets have been utilized the channels. This has in the securement of been somewhat costly and as to the compartment forming rods, it has been found in actual practi ce that the outer headed ends of the rods, which extend through the walls of the case, often protrude slightly beyond the outer surfaces of the walls and channels and form protuberances which person handling the case or are apt to scratch a to tear his clothing.

It is, therefore, the primary object of the present invention to provide a shipping case construction wherein the use of rivets for some of the angles and channels is eliminated by the arrangement and construction of t he compartment forming rods whereby the same serve in lieu of rivets,

rods

are so formed and arranged that any hazard as to the ends of the same projecting beyond the outer surface por'- tions of the case is entirely eliminated.

A further object of the invention is to provide a shipping case wherein the compartment forming rods are formed with heads inwardly of the rods so constructed that in addition to forming compartments, said rods reenforce and strengthen the walls of the case to than in the ordinary case rivet or securing means angles, provide for better a much greater degree construction, serve as for the channels and heading on the outer ends of the rods against outer surface portions of the case, and prevent working of the rod ends.

loose or protrusion A further object of the invention is to provide a compartment forming rod construction for shipping cases wherein the ro ds, as formed and arranged, have unusual rigidity and will not distort with respect to the case, and furthermore, support the walls of the case against inward and outward strains and flexing regardless of whether the case walls are formed of wood or of metal.

A further object of the invention is to provide compartment forming rods for shipping cases which rods are formed at their end portions with spaced heads abutting respectively tightly against the outer and inner surfaces of the case, and where said rods pass through the edge reenforcing channels they serve to clamp the channels between the heads and into secure engagement with the case wall portions.

A further object of the invention is to provide a shipping case construction of the class described 'whichis of very simple construction, is inexpensive. to manufacture, is strong and durable, and is well adapted for the purposes described.

With the above and other objects in view, the invention consists of the improved shipping case, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a plan view of the improved shipping case;

Fig. 2 is a vertical cross sectional view thereof taken 'on line 2-2 of Fig. 1;

' Fig. 3 is a fragmentary detail sectional view taken on line 3-3 of Fig. 2;

Fig. 4 is an enlarged fragmentary detail sectional view illustrating one form of partition rod and its construction and relation with respect to opposed walls of the case;

Fig. 5 is a similar view of another form of partition rod formed only with heads or shoulders in abutment with inner surfaces of the case walls; and Fig. 6 is a similar View of still another alternative form of construction insofar as the rods and case walls are concerned.

Referring now more particularly to the draw ing, it will be seen that the box or case consists of a four-sided wooden body composed of sides 8 and ends 9. The lower edges of the sides and ends are reduced and are covered by metal reenforcing and protecting channels 10, while the upper edges of the ends 9 are similarly reduced and covered by metallic channels 12, the latter being secured in place by rivets 13. The corners of the case are protected and covered by external vertical metallic angle bands 14 and interior metallic angle bands 15, and each pair of bands 14 and 15 overlap and cover the end portion of a channel member 10 or 12. Within the upper corner portions of the case are box engaging brackets 16, and the upper channels 12, the upper portions of the angle bands 14 and 15 and said brackets 16 are secured to the upper wall portions by rivets 17.

The interior of the case is divided into a plurality of compartments by longitudinal and transverse rods 18 and 19 arranged in spaced relation and in different horizontal planes. The end portions of all of said rods are extended, in the principal form of the invention, through the ends and sides of the case, respectively and the extreme outer ends are headed, as at 20, to prevent withdrawal. In addition to said heads 20, all of the rods, inwardly thereon to the extent of the thickness of the case wall, are formed with inner heads or flanges 21 which abut directly against the inner surface of the case wall, or the angle band or channel, as the case may be. Pairs of the lower longitudinal rods 18 form the bottoms of the compartments of the case and said lower longitudinal rods, intermediate their ends, extend through and are supported by transverse metallic strips 22 formed with angularly flanged end portions 22' which abut against and are secured to the inner faces of the lower longitudinal channels 10 by rivets 23.

The end portions of the lowermost longitudinal rods 18 extend through the lower end channels 10 in addition to the walls 9, as shown most clearly in Fig. 3, and the heads 20 and 21 on said rods abut respectively against outer and inner surfaces of the channels and clamp said channels onto the end wall portions, and in addition, said rod portions serve as rivet or securing means for said lower end channels. The outermost lower longitudinal rods 18 extend at their end portions, in addition, through the outer and inner vertical angle bands 14 and 15, and serve as rivet or securing means therefor. This is also true of the outermost transverse as well as horizontal rods in the higher planes. Other rods, in the principal form of the invention, which extend through non-reenforced wall portions, carry inwardly of their outermost heads 20, washers 24 disposed in countersunk recesses 25 therefor, as shown especially in Fig. 4. The rods 18 and 19 in the upper plane may, if desired, be tied together at their points of crossing by metallic bracket plates 26 known as icers.

Fig. 5 illustrates an alternative arrangement which is applicable to some or all of the rods 18 or 19. As shown, a rod is only formed with inner heads 21 inwardly of the ends of the rod. The rod end portions 27, outwardly of the heads 21 do not extend entirely through the walls 8, but merely a substantial distance thereinto. Due to the inner heads 21 in abutment with the inner surfaces of the walls 8, the rod can not work loose nor shift, and it will effectively brace and reenforce the walls. This arrangement has the advantage of eliminating any heading, so far as the rods are concerned, on the exterior of the case.

A further alternative rod arrangement is illustrated in Fig. 6 wherein the washers and countersunk recesses shown in Fig. 4 are eliminated and the rod end portions have spaced inner and outer heads 20 and 21 with the outer heads disposed directly against the outer surface of the case walls.

Although the improved compartment forming rod construction has been illustrated in connection with a case composed of wooden ends and sides, the construction is equally applicable to metallic cases. In fact it would be especially advantageous in a metal case due to the usual flexing of the metal walls which would be overcome to a great extent by virtue of the reenforcement and bracing efiected by the improved rod construction with the inner heads in addition to or independent of the outer heads.

From the foregoing description it will be seen that in the improvedshipping case construction the compartment forming rods serve as rivet or securing means for the metallic reenforcing channels and angle bands, reenforce the case ends and sides, impart rigidity to the entire structure, and the arrangement is also such that the ends of the rods can not protrude from the outer surfaces of the case to be hazardous. Where outer heads are formed on the ends of the rods, said heads may be formed larger and more effectively than in prior constructions because of the backing up afforded by the inner heads. The improved shipping case construction is furthermore simple and novel, and is well adapted for the purposes set forth.

What I claim as my invention is:

1. In combination, a pair of spaced-apart container walls having pockets therein, and a rod extending between said walls and having its end portions extending into a pair of opposite pockets but terminating a substantial distance short of the inner ends of said pockets, the end portions of said rod, inwardly of the extremities, being formed with shoulders contacting with inner surface portions of said walls.

2. A shipping case, comprising a four sided Wooden body, metal reenforcing channels enclosing lower edge portions of an opposed pair of the body sides, and a bottom rod having its end portions extended through said sides and both walls of the channels and formed on both sides of the channels with pairs of spaced heads contacting with outer and inner faces of said channels to secure said channels to the body sides.

3. A shipping case, comprising a four sided wooden body, metallic reenforcing members enclosing inner and outer face portions of said walls, and a partition forming rod between opposite sides of the body and having its end portions projected entirely through said opposite walls and entirely through said reenforcing members, the end portions of the rod being formed on both sides of a wall with pairs of spaced heads contacting with exposed faces of reenforcing members and clamping the reenforcing members therebetween and to a wall portion.
